Yi Hong, Ph.D.

Dr. Hong specializes in electrical testing and failure analysis of consumer electronics and semiconductor devices. He has 5 years experience in fabrication, characterization, and simulation of semiconductor devices including organic semiconductor devices, semiconductor nanowire devices, and polycrystalline and amorphous silicon thin film devices. Dr. Hong’s background also includes experience in acoustics, nondestructive evaluation, and instrumentation.

He has extensive experiences with material characterizations (SEM, AFM, Raman and UV-ViS spectroscopy, etc.); device characterization (DC/AC/CV); clean room processing; and design, fabrication, numerical simulation, and failure analysis of semiconductor devices, particularly thin film transistors (TFT).

Prior to joining Exponent, Dr. Hong was a postdoctoral research assistant at the NSF National Nanotechnology Applications and Career Knowledge Center at Pennsylvania State University, where he participated in fabricating and modeling high performance silicon nanowire transistors. He received a Ph.D. in electrical engineering from Cambridge University in 2007, where his research was focused on simulation and characterization of organic thin film transistors.
